Abstract

Poor urban microclimate and thermal comfort has contributed a continues urban energy issue. The urban energy imbalance is caused by the uncontrolled urban development and ignorance to the urban environmental damages. The configuration of urban spaces and development play significant role in the level of urban thermal heat. The high intensity of solar radiation in tropical region makes the urban thermal discomfort a major challenge in creating a comfortable and lively outdoor urban space. The lacking of firmed studies on the relationship of urban configuration and microclimate were the initial background of this study. This study aims to investigate the long wave radiation behavior in four scenario of urban canyon directions. This study was situated in high density residential area of Kuala Lumpur, Malaysia using the ENVI-met V 3.1 simulation. The finding indicated that the East–West direction received inconsistent pattern and significant intensity of long wave radiation over the South-North. This study suggests the strategized and the passive design of urban form to be considered for achieving the climatically responsive urban configuration in the tropical context.
